The relation of acrodermatitis continua suppurative(Hallopeau) to psoriasis is controversial. However, some consider it as a localized form of psoriasis characterized by pustules limited to one or a few fingertips including the nail bed. Nail loss is not uncommon. Here we present a typical case of acrodermatitis continua of Hallopeau characterized by chronic inflammation and pustulation confined to one finger (thumb) with nail loss of more rhan three years duration.
A 38-year-old man presented with asymptomatic, bilateral symmetrical, well-demarcated, red scaly plaques confined to both palms of many years duration with sustained exacerbations and exceptional remissions.
A 20-year-old female suffered various manifestations of neurofibromatosis-1 since early childhood. The presented photo shows large irregular cafe-au-lait on the trunk which has been noted since birth.
Since birth an extra small digit arose from the ulnar side of the base of the left fifth finger had been noticed. The extra digit was rudimentary and comprised of skin only (skin tag -like). It lacked bone structure or nail unit. It was an isolated congenital anomaly without associated skeletal, cardiovascular or other defect.
An asymptomatic linear band of brown-black discoloration extending from the base of the fifth fingernail to the distal end of an about one and half year duration in a 22-year-old female. Biopsy of the nail matrix at the site of pigmentation revealed a benign melanocytic nevus.
A 35-year-old female presented with a slate-grey to bluish hyperpigmented patch affected the right side of the face mainly the area supplied by the maxillary branch of the trigeminal nerve was noticed since birth. The conjunctiva, sclera and the skin surrounding the eye were not involved.
A 55-year-old man presented with asymptomatic, bilateral, well-demarcated, fiery-red, scaly plaques involved both shins of many years duration. The scalp and trunk were also involved.
